350mm to 600mm
The ball lock method is used to simplify replacement of the
seat ring.
Easy replacement of the seat ring
When the disc rotates, it unseats at a small open angle by its
cam effect. It prevents seat abrasion and provides perfect
shut-off for a long period.
Double eccentric geometry
Seals flow in both directions. Valve can be used even if the
flow changes direction. (There are pressure limitations for
each direction of flow. See chart below for recommended
specifications.)
